The Underwood 38+P I carry in my J-frame snubby advertise a 125 grain XTP at 1,250 which is about 100 fps faster than a 124 grain 9mm round.

I wouldn't believe those numbers. That is 357mag numbers. Underwood probably tested with a 6" barrel to get that. Anything full weight over 1000fps in a snub is super hot

Compared to the ubiquitous 9mm, .30 SC looks like a good round with the advantage of being able to fit more rounds in a magazine of a set volume. Especially helpful in free states that allow more than 10 rounds in a magazine.
Will the advantage of having the stopping power of a 9mm with higher magazine capacity be enough to overcome 9mm's 120-year head start?

In the spirit of apples to apples, what does a 9mm do in a 1.75" barrel?

Interesting question. There really isn't much difference in the length of the barrel when you consider that auto pistol barrel lengths include the chamber. Looking at it this way, if I measure my Ruger LCR .38 from the back of the cylinder to the muzzle it's 3.25" +/-, pretty close to the 3.1" Shield. The revolver is likely to lose here due to the barrel/cylinder gap, and the fact that the hop between the bullet and the start of the rifling is somewhat farther than it is in an auto. But in the end the comparison looks closer than it appears just looking at "barrel length".

It's likely to be the next "Bambi Secret Agent" weapon of choice.
I chronyed and that load was about 1150 in 4" model 15. Got some voodoo going on there.

After the first year, S&W pretty much silent on the 30 Super carry. Not much promotion and no further models. At least Hi point tried a carbine. Just like the . 327 mag, which S&W gave up on too fast.

Voodoo is a form of magic. There is no such thing as magic.
Higher velocity is the result of higher pressure. If you see a 38 load hotter than others that means it is loaded to higher pressure levels.
Choosing the right powder to maintain pressure as long as possible helps but all ammo makers do that, as any reloader will tell you it isn't hard to do.
If you are unwilling to believe a company's performance claims without independent verification you shouldn't take their word about pressure levels either. Most people that buy ammo from Underwood or Buffalo Bore do so because it is the hottest ammo available. They have a strong financial motive to err on the side of more pressure.
It is a figure of speech genius.

I buy the Underwood 38+P because I don't enjoy shooting .357 loads out of my Scandium snubby. Not worried about 38+P pressures. Shorter cases make ejection easier also with the short rod on a snubby.

I do the same thing with my magnum revolvers. With factory ammo there is a big gap between +P and magnum. The hot +P loads from UW and BB fill the gap nicely.
Until a fire destroyed their building Georgia Arms was my go to source for in between power level ammo. In particular they made a 240 Grain FMJ in a 44 Magnum rated case rated at 1000 fps I thought was near perfect for my M69. Strong enough to be interesting but not so punishing I wanted to quit after a cylinder or two. A lot of their magnum ammo with hard cast or JHP bullets was also somewhere between +P and true magnum in terms of power. If they ever recover from the fire and start making ammo again they are worth a look. Same power levels but less expensive than UW and much less expensive than BB.

Careful with +P in a Model 15. You don't want to potentially damage a fine old revolver. Some might reply that S&W made K-frame .357's, but those used different steel in the cylinders and you will recall they had forcing cone cracking issues.

I'm glad to see the industry is still innovating.
I'm a fan of 32 caliber, and 30sc is a big step up in non rimmed ammo in .312 for semiauto pistols.
I consider 32 a better handgun caliber than 38.
But 38 has a huge head start in the market.
Can't buy a new 30sc gun here in CA yet, but I will when it becomes possible.

This I think is ultimately the issue. Nothing especially "wrong" with the 30 SC (just as there was nothing wrong with previous .30 auto cartridges, like the old Luger, Tokarev,French "long" and possibly others.). Those old time rounds are ballistically very similar to the best new thing. I personally like small bores and had high hopes for both the .32 H&R Mag and the .327. How ever neither of those made it to mainstream and I suspect the SC will go the same way. As long as ammo is 3x the price of 9mm while offering no real advantage the round is DOA. Same with the 5.7 (though it does have a bigger following than the.30.)
Why small bores like the 5.7 ever make it at all is beyond me. Buddy has a 5.7 Ruger. It's a fun gun to shoot, but ammo is $$$. I can have as much fun plinking with ammo that's a lot less pricey. Heck I can load .44's for WAY less $$$. I enjoy new things, but to be a commercial success requires volume, and without volume prices will always be high. I love the 7.5 FK, but I'll never own one for the exact same reason.
What can the .32 caliber do that a 38 caliber can't?
357 magnum 125 jhp is widely accepted as the best handgun manstopper made.
And with the right ammo you can also hunt deer and hogs with it.
Ther isn't anything you can do with a .32 handgun that you can`t do with a .38 handgun better.
